Each telefilm in The Classic Ghosts series (a total of five episodes) required a grueling 10-day production schedule, from start to finish. Each show rehearsed for six days and then filmed for four. While filming was taking place on one show, another show would be in rehearsals. The entire package of five telefilms was completed in six weeks.
A February 10, 1973 article in the New York Times ("Distaff Production Team More Than Tokenism") notes that the crew of The Classic Ghosts series included women working on all facets of the production, as grips, assistant directors, production supervisors and more, which was a relatively rare occurrence in that era.
The Classic Ghosts series is noteworthy as an early production featuring a creative and technical team largely led by women, a number of whom were pioneers in television. Produced by Emmy-winner Jacqueline Babbin (Sybil), the series employed highly-accomplished, prolific directors, Lela Swift (Dark Shadows) and Gloria Monty (General Hospital), both of whom had long worked in numerous capacities in TV, ultimately producing and helming hundreds of hours of network programming in their groundbreaking careers.
Preserved in the UCLA Film & Television Archive, The Screaming Skull received a rare public (online) showing in October 2020, as part of the Archive Television Treasures series.
The Classic Ghosts limited-run anthology series of five telefilms was not a ratings success for ABC, but the original broadcasts (mostly unseen since their original airings) have achieved a minor cult-status among classic TV horror fans.
